If your kids enjoyed other books from "The 39 Clues" series, they want be disappointed. To me this series is like a pack of vitamin candies - kids love them, you know there is not much nutritional value in them, but you yield once in a while (in this case "vitamins" are some geography and history).

This book is good for learning Geography - I keep hearing about places and end up looking them up on Google Earth.

What did you like best about this story?

Solid story, well laid out. There were times when I said to myself, "Really?" because the kids do a few things that are dumb that make the story a bit more predictable. However, the backstory with the Dad is great.

What about David Pittu’s performance did you like?

David Pittu is one of the best. The voices are very distinctive, and easy to listen to. Also, the production is top notch. Some audiobooks have obvious cuts and pops, and the sound quality can be rough, but not so with this company. The clarity and even the music are both perfect for this reading.
